Description

Technical Field

[0001] This utility model relates to the field of vacuum melting equipment technology, and in particular to a melting chamber door assembly. Background Technology

[0002] Vacuum precision casting furnaces are key equipment for producing high-end metallic materials, and their melting chamber doors must have functions such as opening, closing, and tilting for material discharge. Currently, existing melting chamber door tilting devices have the following significant drawbacks: First, its structural layout is usually loose, with components such as drive mechanisms (such as hydraulic stations and motors) and transmission mechanisms scattered around the door, resulting in low space utilization, an overall lack of compactness, and a significant amount of usable space occupied by the equipment.

[0003] Secondly, due to the dispersed structure, a large number of mechanical and hydraulic electrical components are directly exposed to the high-temperature and dusty smelting workshop environment. They are very susceptible to aging, damage or failure due to high-temperature radiation, metal splashes or dust intrusion, which poses serious safety hazards and reduces the overall reliability and service life of the system.

[0004] Finally, the equipment's cooling water pipes and power control cables lack effective integrated management and protection measures. They are typically simply bundled or suspended, making them highly susceptible to excessive bending, friction, and even tearing during repeated tilting movements of the door, leading to coolant leaks or circuit failures. In the event of an internal coolant leak, if it cannot be drained in time, it may splash onto the high-temperature melting chamber or electrical components, causing a safety accident.

[0005] Therefore, there is an urgent need for a smelting chamber door assembly that is compact, has good protection, and is safe and reliable in operation, in order to solve the above-mentioned technical problems. Utility Model Content

The drive unit is fixed to the mounting base by the drive mounting seat, and the drive unit is located away from the central area of ​​the door frame. The integral protective cover is installed on the outside of the melting coil mechanism and connected to the door frame. The outline of the integral protective cover is adapted to the layout of the melting coil mechanism. The flow guiding and protection mechanism is located at the bottom of one end of the melting coil mechanism. The flow guiding and protection mechanism has a coolant channel inside, and the two ends of the coolant channel are respectively connected to the water inlet and water outlet located at the bottom of the door frame. The outer contour of the current guiding and protection mechanism is an arc-shaped structure, and the interior forms a cable guide channel for guiding and accommodating the water-cooled cable.

[0008] As a further technical solution of this utility model: the drive mounting base and the mounting base are integrally formed or connected separately by fasteners.

This utility model has advantages such as compact structure, safety and reliability, and long service life, and is particularly suitable for vacuum melting equipment in high-temperature and harsh environments.

[0016] 2. Integration and Space Optimization: By setting a unified mounting base and offsetting the drive unit, the components are centralized and modularly installed, which greatly optimizes the space layout, makes the structure more compact, and reduces the overall footprint of the equipment.

[0027] Example 1: Reference Figures 1-3This utility model discloses a melting chamber door assembly, including a door frame 1, a tilting drive device 2, and a translation mechanism 3. It also includes a drive mounting base 4, a mounting base 5, a flow guiding and protection mechanism 6, an integral protective cover 7, and a melting coil mechanism 8. The door frame 1 seals the melting chamber, and the mounting base 5 is fixedly mounted on the outer surface of the door frame 1. The tilting drive device 2 includes a drive unit and an execution unit. The drive unit is fixed to the mounting base 5 via the drive mounting base 4, and the drive unit is positioned away from the center area of ​​the door frame 1. In this embodiment, the translation mechanism 3 is used to realize the left and right translation of the coil, thereby changing the rotation point and pouring point of the coil, thus enabling the pouring of mold shells and coils of different sizes.

[0028] An integral protective cover 7 is installed on the outside of the melting coil mechanism 8 and connected to the door frame 1. The outline of the integral protective cover 7 is adapted to the layout of the melting coil mechanism 8. The flow guiding protection mechanism 6 is located at the bottom of one end of the melting coil mechanism 8. The flow guiding protection mechanism 6 has a coolant channel inside. The two ends of the coolant channel are connected to the water inlet 13 and the water outlet 14 located at the bottom of the door frame 1, respectively. The outer outline of the flow guiding protection mechanism 6 is an arc-shaped structure, and the inside forms a cable guide channel 61 for guiding and accommodating water-cooled cables.

[0029] A limiting device 15 is provided on the door frame 1, and the door frame 1 serves as the load-bearing foundation of the entire assembly. The mounting base 5 is fixedly welded to the outer side of the door frame 1, providing a unified installation platform for subsequent components. The drive unit is fixed to the mounting base 5 via a drive mounting seat 4, and its installation position is optimized, located in the edge area of ​​the door frame 1, thereby making full use of the space around the door, making the overall structure more compact, and away from the core area of ​​the smelting heat source. In this embodiment, the door frame 1 is welded from high-temperature resistant metal material and is used to seal the smelting chamber. The mounting base 5 is a thick steel plate component, fixed to one side of the outer surface of the door frame 1 by welding.

[0030] The tilting drive unit 2 includes a servo motor and a reducer connected to the servo motor for transmission, and the actuator is connected to the tilting mechanism. The drive unit is fixedly mounted on the upper edge of the mounting base 5 via the drive mounting seat 4, so that it is away from the central high-temperature zone of the door frame 1.

[0031] The integrated protective cover 7 is installed outside the actuator and is detachably connected to the door frame 1. This integrated protective cover 7 completely encloses the originally exposed melting coil mechanism 8, which not only provides safety protection and dust and splash protection, but its streamlined design also makes the equipment look cleaner and more aesthetically pleasing.

[0032] The current guiding and protection mechanism 6 includes a top plate 62, two arc-shaped plates 63, and a water-cooled cable protection plate 64. The top plate 62 is fixed to the bottom of the integral protective cover 7. The two arc-shaped plates 63 are symmetrically fixed on both sides of the top plate 62. The water-cooled cable protection plate 64 is fixed between the two arc-shaped plates 63. The two arc-shaped plates 63, the top plate 62, and the water-cooled cable protection plate 64 form a cable guiding channel 61.

[0033] The flow guiding and protection mechanism 6 is fixedly mounted on the mounting base 5 and located at the bottom of the melting coil mechanism 8. This mechanism is one of the core innovations of this utility model. It adopts a double-layer functional design: the interior has a coolant channel for the flow of cooling water, and a water injection interface is provided on it, which is connected to the water injection port 13 at the bottom of the door frame 1. The exterior is designed as a smooth arc-shaped structure, naturally forming a channel for guiding and accommodating the water-cooled cable. In the event of an internal leak, the leaked coolant can be guided to a safe location by its internal structure to discharge, avoiding damage to the equipment; when the equipment is tilted, its arc-shaped outline can limit and guide the water-cooled cable, effectively preventing damage such as sharp bends and friction to the cable.

[0034] The drive mounting base 4 and the mounting base 5 are either integrally formed or connected separately by fasteners. The integral protective cover 7 is formed by stamping metal sheet, and its surface is coated with a high-temperature resistant and corrosion-resistant coating. Two hinges 11 are installed on one side of the door frame 1, and a quick-release clamp 12 is installed on the side of the door frame 1 away from the hinges 11.

[0035] The integrated protective cover 7 is made of stainless steel sheet by stamping. Its shape is designed according to the outline of the melting coil mechanism 8. It is connected to the door frame 1 by bolts, completely covering the melting coil mechanism 8 and forming a smooth, streamlined appearance.

[0036] The current guiding and protection mechanism 6 is a semi-circular arc-shaped plate 63 made of stainless steel, which is fixed to the side of the mounting base 5 by welding. Its external semi-circular arc structure naturally forms a cable guiding channel 61, along which the water-cooled cable can be laid and moved smoothly.

[0037] Working principle: When the equipment needs to be tilted, the drive unit activates, pushing the actuator to complete the tilting operation. During this process, the water-cooled cable slides within the cable guide channel 61 of the flow protection mechanism 6, preventing sharp bends. If a leak occurs in the cooling system, the liquid will flow into the coolant channel and be discharged directionally to a safe area through the drain hole at the bottom, preventing splashing onto the high-temperature door body or electrical components.

[0038] The implementation principle of this utility model is as follows: This utility model discloses a melting chamber door assembly, including a door frame 1, a mounting base 5, a tilting drive device 2, an integrated protective cover 7, a melting coil mechanism 8, and a flow guiding protection mechanism 6. The drive unit of the tilting drive device 2 is offset to the outside of the door frame 1 via the mounting base 5, optimizing the spatial layout. The integrated protective cover 7 encloses all exposed components of the melting coil mechanism 8, enhancing protection. The innovative flow guiding protection mechanism 6 integrates an internal coolant leakage guiding channel and external cable guiding protection functions, simultaneously solving leakage safety hazards and cable wear problems. This utility model has advantages such as compact structure, safety and reliability, and long service life, and is particularly suitable for vacuum melting equipment in high-temperature and harsh environments.

[0039] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
